Coating & Drying Equipment

Coating step is where slurry is applied to a current collector foil (typically copper or aluminium) using tools such as a slot die, doctor blade, or anilox roller. Coating can be performed in a continuous or intermittent manner and may be applied to one or both sides of the foil—either sequentially or in a tandem coating setup.

After coating, the foil passes through a drying channel where controlled heat evaporates the solvent. The coated web is then transported via rollers or non-contact levitation systems, and rewound onto an inner core for transfer to the next process step. Environmental controls are critical to prevent dust, moisture, or thermal instability from affecting coating quality.

Key configurations of coating equipment to consider

• Slot-Die Coating System - For highly precise, repeatable coatings on narrow webs.
• Doctor Blade Coating System - Cost-effective setup for flexible material development.
• Integrated Flotation Dryer - Ensures gentle, uniform, non-contact drying of sensitive coatings.
• Solvent-Compatible Module with LEL Monitoring - Safe operation with solvent-based slurries, preventing explosion risks.
• Customized Web Handling & Tension Control - Guarantees uniform thickness and high reproducibility across samples.
